This is a follow up study for patients that participated in a previous ABT-333 study. There is no treatment provided and only blood samples for resistance are collected.

Condition Intervention Phase
HCV Infection
Procedure: Blood sample collection only
Drug: ABT-333
Phase 2

Study Type: Interventional
Study Design: Allocation: Non-Randomized
Intervention Model: Single Group Assignment
Masking: Open Label
Official Title: A Follow-up Study to Assess the Evolution and Persistence of Resistance to ABT-333 After Discontinuation of ABT-333 Therapy in HCV Genotype-1 Infected Subjects Who Participated in Phase 1, 2, or 3 ABT-333 Clinical Studies

Further study details as provided by AbbVie:

Primary Outcome Measures:
  • Analysis of the prevalence of resistance of specific mutations over time will be summarized. [ Time Frame: Approximately 48 Weeks ] [ Designated as safety issue: Yes ]
  • Analysis of the degree of phenotypic resistance (fold change in susceptibility to ABT-333 compared to wild-type virus) will also be summarized. [ Time Frame: Approximately 48 Weeks ] [ Designated as safety issue: Yes ]

Secondary Outcome Measures:
  • Summary of serious adverse events related to study procedures only. [ Time Frame: Approximately 48 weeks. ] [ Designated as safety issue: Yes ]

Enrollment: 35

Study Completion Date: May 2010
Primary Completion Date: May 2010 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Follow-up study that includes sample collection procedures only and no treatment.
Procedure: Blood sample collection only
Approximately monthly collection of blood samples
Drug: ABT-333
Previous treatment in prior ABT-333 studies. Follow up study that includes sample collection procedures only and no treatment.
